Ihave a cs800x. It has been in storage but recently I have had to crack it back out.

The fan is a 2 speed fan. After some use the fan stopped working. I know that the Nidec 450 is obsolete. I would like to know a good replacement for this fan that would move more air. The unit has been cleaned and works well other than the fan. Thank you.

Call Peavey, IF and WHEN you get through they'll have something. Prices are USUALLY pretty good too. It IS the fan that is bad right? Some of those models had a fairly large resistor in the fan circuit that runs pretty damn hot if I remember correctly, overheated/broken solder joints is the result.

I am sure it is the Fans. They are suppossed to run at a low speed until hot and then run at the higher level. This won't even start up when first powered on. You can hear it try to engage but it doesn't start.

Peavey does have the exact fan but was hoping for an aftermarket if possible. Peavey makes it next to impossible to order as there is no online ordering option and being on the west Coast, the Misssissippi hours are brutal.

You're better off using the right fan for this, otherwise you may not get the low speed to work anyway, as it's current controlled, so the speed of the fan on 'low' will depend on the windings in the fan. The wrong fan may either run too fast when cool (not so much a problem) or fail to start at all when cool.

Craig is right, theres a large 20W resistor to drop the current down in 'cool' which is shorted out when 'hot'.

PV opens at 8AM central time and is there until 5PM. That is 10AM to 7PM pacific. Seems reasonable. the time to call them is right when they open, that is when the phones are least busy there.

Have you actually extracted the fan and applied working voltage to it directly?

There is a 400 ohm 15-20 watt resistor in series with the fan, then a triac to short across that resistor when the temperature sensors tells it to. If that resistor breaks a lead, the fan won't run until the amp gets real hot.
